PRIOR ART

Toothbrush systems which allow for the rotation of the toothbrushbristles are known in the art. The best prior art known to Applicantincludes U.S. Pat. Nos. 4,963,046; 3,022,789; 3,825,354; 3,261,367;4,332,497; 4,955,567; 4,759,383; 4,296,071; 3,549,268; 4,467,822;4,583,563; 2,184,212; 4,950,247; 2,546,754; and, 3,892,237.

In some prior art systems such as that shown in U.S. Pat. No. 4,963,046,there are cartridge-type storage portions which are removably connectedto the toothbrush system. Additionally, such prior art systems showcommunication passages for supplying the oral use fluid from the storageto the bristle implanted surface on the brush base. However, such priorart systems do not provide for the pulsating type of cleansing liquidflow which is advantageous to the removal of contaminants within themouth of a user. Additionally, such prior art systems do not show thesimultaneous pulsating fluid flow in combination with the multiplicityof rotational planes for the bristles during use.

Other prior art systems such as that shown in U.S. Pat. No. 3,022,789provide for injector-type toothbrushes for receiving toothpaste from ahigh pressure system such as an aerosol bomb. Such do provide for ahollow type toothbrush with a detachable injector however, such do notprovide for the combination of bristle rotations in a plurality ofplanes with the pulsating fluid flow of the subject system.

Other prior art such as that shown in U.S. Pat. No. 3,825,354 describetoothbrush adaptors for aerosol containers however, such do not providefor the advantageous pulsating fluid flow as is necessary to the subjectsystem.

Basically, there are prior art systems which include rotating heads asbristles which are advantageous for application to specific gum or toothareas and include heads that oscillate through an approximate 90° angle.However, although sufficient for cleaning generally flat surfaces, suchprior art is disadvantageous for arcuate surfaces of teeth and cannotclean well between a user's teeth.

Other prior art systems include rotating bristles which are advantageousfor application between teeth, but are not efficient for cleaning flatareas, and in some cases may be abrasive to gum tissue.

Such prior art systems do not provide for the advantageous bristlerotation and oscillatory displacement in separate planes simultaneouslywhile providing a stream and spray of cleansing liquid to removecontaminants wherein the overall system is self-refilling, wireless andtubeless.

Additionally, prior art systems do not provide for a stationary headhousing allowing the bristles to be reciprocally and reversiblydisplaced which provides the user additional comfort during the brushingoperation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to FIGS. 1-8, there is shown toothbrush system 10 foroptimizing removal of contaminants from the teeth and gums of a user. Aswill be described in following paragraphs, system 10 provides the userwith the maximization of bristle-tooth interface while simultaneouslyproviding a fluid force to remove unwanted contaminants. Additionally,system 10 provides the user with a completely portable system devoid ofhook-up tubes and connectors.

In particular, toothbrush system 10 provides for a multiplicity ofrotational and oscillatory displacements of bristles 20 to be furtherdescribed in following paragraphs. Additionally, and simultaneous to theplurality of displacements of bristles 20, there is provided mechanismswhereby a cleansing liquid is actuated to provide a pulsating flowthrough and adjacent bristles 20 which are being displaced in aplurality of planes. In this manner, contaminants are effectivelyremoved from the surface of the teeth by the combined brushing actionand removed by the liquid spray and flow.

It is to be understood that the term cleansing liquid hereinafterreferred to in following paragraphs may refer to general types ofcleansing liquids such as plaque fighting liquids, dentrifice typeliquids, or simply salt water solutions, not important to the inventiveconcept as is herein described.

Referring to FIGS. 1, 2 and 4, there is seen that toothbrush system 10includes handle member 14 having internal handle chamber 22. As can beseen, handle member 14 extends in longitudinal direction 18 as definedby the directional arrow shown in FIGS. 1 and 2. Handle member 14 may beformed of one-piece or multi-piece molded plastic or some like materialnot important to the inventive concept as herein described with theexception that it have a diameter which allows a user to easily holdtoothbrush system 10 in one hand during a normal brushing operation.

Handle member 14 may include a standard commercially available on/offswitch (not shown) for activating motor 40 responsive to electricalinput from standard batteries 42 and may further include a push buttonvalve to control fluid flow. Such electrical switches and valves arewell known in the prior art and are not part of the invention concept asherein described.

Head member 12 also extends in longitudinal direction 18 and defineshead housing 24 and includes sets of bristles 20 extending external headhousing 24, more clearly seen in FIGS. 2, 4 and 5. Head member 12 andassociated housing 24 may be integrally molded or may be releasablysecured to handle member 14 through a standard keyway interface notimportant to the invention concept as herein described with theexception that head housing 24 be removable from handle member 14. Headhousing 24 in a manner similar to handle member 14 may be formed of aplastic type composition and may be molded in one or multi-pieceformation.

Toothbrush system 10 includes liquid container 28 shown in FIGS. 1, 2and 6 as well as partially shown in FIGS. 7 and 8 to provide adispensing container for the cleansing liquid. Liquid container 28 ismounted within internal handle chamber 22 for dispensing the liquidresponsive to a pressure differential created when the toothbrush systemis actuated. Liquid container 28 is formed of a flexible bellows typecontour and is in fluid communication with head member 12 as will befurther described in following paragraphs. Bellows type liquid container28 may be formed of a flexible material such as a plastic composition orsome like composition which is inert to the cleansing liquid containedtherein. Bellows container 28 is collapsible as cleansing liquid isdispensed therefrom and may be expanded when filled with cleansingliquid as will be described in following paragraphs when taken withrelation to FIGS. 6-8.

Bellows container 28 is secured to bottom wall 30 of handle member 14.As can be seen in FIGS. 1 and 2, liquid container 28 includes containerconduit 32 formed through bottom wall 30 of handle member 14 and furtherincludes trap door member 34 which is rotatable with respect tocontainer conduit 32 through container hinge 36. Hinge 36 may be astandard spring hinge which is biased in a manner to block or close thecontainer conduit passageway during use but may cause opening of trapdoor 34 upon application of pressure.

Other types of self sealing devices may be used and the inventiveconcept is not limited to the description herein described. In thismanner, and as will be more fully described in following paragraphs,cleansing liquid may be inserted through container conduit 32 to theinternal portion of liquid container 28 to fill liquid container 28.However, trap door member 34 does not allow egress of cleansing liquidcontained in liquid container 28 since it maintains a closed state whentoothbrush system 10 is in operation.

Toothbrush system 10 further includes drive mechanism 38 seen in FIGS. 1and 2 which allows for the portability of toothbrush system 10 whilemaintaining a high torque actuation and displacement operation. Drivemechanism 38 is mounted within internal handle chamber 22 fordisplaceably oscillating bristles 20 while simultaneously allowingrotation of bristles 20 and further delivering the cleansing liquidexternal head housing 24. Drive mechanism 38 includes a standard DC hightorque motor 40 which is commercially available and utilizedcommercially in a number of portable toothbrush systems. Additionally,drive mechanism 38 includes standard batteries 42 which may berechargeable for providing electrical energy to drive motor 40 andcorresponding motor shaft 44. For ease of replaceability for the user,batteries 42 may be provided in a battery pack housing 26, insertableinto chamber 22 in total without the necessity of the user changingindividual batteries 42.

Toothbrush system 10 includes liquid delivery mechanism 46 clearly seenin FIG. 1 and FIG. 3. Liquid delivery mechanism 46 includes first liquidconduit 48 shown in FIGS. 1 and 2 which is in fluid communication withliquid container 28 at first liquid conduit first end 50. Additionally,liquid delivery mechanism 46 further includes second liquid conduit 52which is in fluid communication with head flow passageway 54 seen inFIGS. 4 and 5. Standard one-way valve 56 is mounted on first liquidconduit second end 58 as is seen in FIG. 1. In this manner, cleansingliquid may be dispensed from liquid container 28 through first liquidconduit 48 and then through one-way valve member 56. One-way valvemember 56 ensures that cleansing liquid will not be passed in a reversemanner into first liquid conduit 48.

Liquid delivery mechanism 46 further includes a mechanism for actuatingone-way valve member 56. As is seen in FIGS. 1 and 3, there is providedlinearly and reversibly displaceable piston member 60 which is coupledto the overall drive mechanism 38 and is displaceable within pistonchamber 62. As is seen, piston chamber 62 is in fluid communication withsecond liquid conduit 52 and one-way valve member 56 on opposinglongitudinal ends as is seen in FIG. 1. Additionally, drive mechanism 38creates a pressure differential between the piston chamber 62 and firstliquid conduit 48 to allow liquid to flow from first liquid conduit 48into piston chamber 62 and then consequently into second liquid conduit52 for dispensation through head flow passageway 54. As can be seen inFIG. 3, as piston member 60 moves in a radial direction toward an outerwall of handle member 14 within internal handle chamber 22, liquidcontained within piston chamber 62 is forced into second liquid conduit52 but is blocked from passage into first liquid conduit 48 by one-wayvalve member 56.

Also included, as shown in FIG. 1, is secondary one-way valve 57 whichis mounted at the entrance of secondary conduit 52 to prevent backflowof fluids and air into piston chamber 62. Thus when a low pressure isprovided in chamber 62, fluids will not pass thereto from conduit 52.

As piston member 60 is linearly displaced within piston chamber 62 in adirection toward central axis 16, a lower pressure is obtained withinpiston chamber 62 which closes valve 57 and opens one-way valve member56 and allows cleansing fluid to be dispensed therein.

As piston chamber 60 reversibly moves in a linear direction withinpiston chamber 62, a pulsating liquid flow is provided through secondliquid conduit 52. As piston 60 moves radially outward, the fluid withinchamber 60 is compressed and a resulting higher pressure ensues. Fluidis then passed into second conduit 52 and not into first liquid conduit48 due to the action of one-way valve 56. This pulsating flow ofcleaning liquid eventually egresses between sets of bristles 20 foroptimizing the removal of contaminants in the user's mouth.

As has been seen and described, piston member 60 is reversibly moved ina linear direction. Toothbrush system 10 further includes a mechanismfor converting the rotational displacement of drive mechanism 38 to thelinear and reversible displacement provided to piston member 60. Themechanism for converting the rotational displacement of drive mechanism38 includes longitudinally extending fork member 64 which includesopposing fork member sidewalls 66 defining longitudinally directed forkslot 68. Fork pin member 70 is slidable within fork slot 68 as is seenin FIGS. 1 and 2. Fork pin member 70 is displaceable within fork slot 68responsive to actuation by drive mechanism 38. Toothbrush system 10includes a mechanism for displacing fork pin member 70 and having firstbevel gear 72 mounted on longitudinally extending motor shaft 44 as isseen in FIG. 2. Second bevel gear 74 is matingly engaged with firstbevel gear 72 for rotation of second bevel gear 74 about a second bevelgear axis which extends normal to longitudinal direction 18. As is seen,fork pin member 70 is secured to an outer surface of second bevel gear74 and extends in a direction substantially parallel to the axis of thesecond bevel gear 74.

Piston member 60 is fixedly secured or molded in one-piece formation toone of opposing fork sidewalls 66 and extends transverse thereto forlinear reversible displacement into piston chamber 62 as has previouslybeen described. Displacement of piston member 60 is responsive to adisplacement of fork pin member 70. Thus, as motor shaft 44 is rotatablydriven by motor 40, first bevel gear 72 is provided with a rotationaldisplacement about central axis 16 of toothbrush system 10. First bevelgear 72 matingly engages second bevel gear 74 which is a right-anglecoupling and results in second bevel gear 74 being rotated about an axissubstantially normal to central axis 16. Fork pin member 70 is mountedoff-center to second bevel gear 74 and as second bevel gear 74 rotates,fork pin member 70 slidably engages fork slot 68 which responsivelydrives piston member 60 in a linear and reversible manner as secondbevel gear 74 rotates.

In this manner, a pulsating flow of cleansing liquid passes from theinternal portion of liquid container 28 through first liquid conduit 48,one-way valve 56, valve 57, and into second liquid conduit 52.

Referring now to FIGS. 4 and 5, there is shown head member 12 andassociated head housing 24. In particular, referring to FIG. 5, there isshown head flow passageway 54 which is in fluid communication withsecond liquid conduit 52 as has hereinbefore been described. Head shaftmember 76 is rotatably mounted in head wall 78 through bearing shaft 80as is seen in FIG. 5. In this manner, head shaft member 76 may rotateabout central axis 16. Additionally, flow of pulsating liquid passesthrough head flow passageway 54 and communicates with branch conduits 82as is shown in FIGS. 5 and 4.

As can be seen in FIG. 4, head slots 84 are formed through head housing24 on an upper portion thereof to allow extension therethrough ofbristles 20. A plurality of head slots 84 are provided as is shown inFIG. 1. In this manner, as will be seen in following paragraphs,bristles 20 are then free to be driven in an oscillating rotativedirection as shown by the directional arrows 86 in FIG. 4 responsive tothe concatenation of elements to be further described.

The mechanism for displaceably oscillating bristles 20 in arcuatedirection 86 includes the extended head shaft member 76 being coupled tolongitudinally directed fork member 64 through ball-slider joint 88shown in FIG. 2. Referring to FIG. 3, as piston member 60 is linearlydisplaced, raceway member 89 is responsively linearly displaced. Ballmember 91 rides within raceway member 89 to cause oscillation of lugmember 93 and responsive oscillation of head shaft member 76. Head shaftmember 76 is journaled in head housing 24 which remains stationary asbristles 20 are oscillated. This combination of elements provides forthe conversion of the displacement of fork member 64 to an oscillatingrotative displacement of longitudinally directed head shaft member 76about central axis 16. This has the resultant effect of providing theoscillating rotative displacement of bristles 20 within respective slots84. As can be seen, as pin member 70 is rotated through thecorresponding rotation of second bevel gear 74, fork member 64 rotateswith respect to head shaft member 76 through ball joint 88 andcorrespondingly displaces head shaft member 76 in the rotativedisplacement about central axis 16.

Referring now to FIGS. 4 and 5 once again, there is provided a mechanismfor rotating bristles 20 about an axis substantially normal tolongitudinal direction 18 and central axis 16. Bristle head members 90extend radially through slots 84 as is seen in FIG. 4. Bristles 20 arefixedly secured to bristle head members 90 through molding or some liketechnique not important to the inventive concept as herein described.Bristle head members 90 are rigidly coupled on a lower end thereof tobristle pinion gears 92 which matingly engage stationary rack gears 94.It is to be understood, that a single stationary rack gear may be usedin combination with mating pinion gears 92 which drive each other.Bristle head members 90 and corresponding bristle pinion gears 92 arerotatable in the direction defined by directional arrow 96 throughbearing core 98. Thus, bristle head members 90 are rotatable indirection 96 with respect to stationary head member 12 when oscillationoccurs in the arcuate direction 86.

In this manner, when head shaft member 76 is rotated in the direction ofarrows 86, bristle head pinion gears 92 matingly engage with rack gears94. Bristle head members 90 are rotatable on bearing core 98 to allowfor rotation of bristles 20 in arcuate direction 96. Thus, asimultaneous movement of bristles 20 is provided through use oftoothbrush system 10 which allows for bristles 20 to be rotated indirection 96 while at the same time oscillating in arcuate direction 86.

Further, and simultaneous with the multiplicity of displacements ofbristles 20, pulsating fluid passes through head flow passageway 54 fromsecond liquid conduit 52 and enters branch conduits 82 formed throughbristle head members 90 as is seen. Pulsating cleansing liquid is thenegressed from head housing 24 external toothbrush system 10.

Referring now to FIGS. 6-8, there is shown toothbrush stand 100 adaptedfor filling liquid container 28 with cleansing liquid. Toothbrush stand100 may be mounted on a base surface or wall mounted and includes standconduit 102 for insert into reservoir 104 which contains the cleansingliquid. Stand conduit 102 is generally U-shaped in contour and isinserted within liquid container 28 through container conduit 32 asprovided in FIG. 1. Stand conduit 102 has opening 106 formed in asidewall thereof which is alignable with opening 108 formed throughsheath member 110 as shown in FIG. 7. Spring member 112 bears againstsheath 110 to maintain conduit opening 106 and sheath opening 108 out ofalignment as is shown in FIG. 8. When liquid container 28 is to befilled, toothbrush system 10 is inserted over stand conduit 102 which isforced against an upper wall of liquid container 28 as shown in FIG. 7.In this condition, openings 106 and 108 are aligned and fluid passesfrom reservoir 104 through conduit 102 and then respectively throughopenings 106 and 108 into the interior of liquid container 28 to providefilling of liquid container 28 with cleansing fluid. When the fillingprocess has been completed, toothbrush system 10 is removed from standconduit and as is seen in FIG. 8. Openings 106 and 108 are misalignedand no fluid from reservoir 104 passes into liquid container 28.Additionally, reverse fluid flow is also terminated.

As is seen in FIG. 6, conduit 102 may include a sharpened end 114 whichis insertable into a lip section of reservoir 104. Reservoir 104 isremovable from toothbrush stand 100 and may be replaced with anotherreservoir 104.

In this manner, there has now been provided a portable toothbrush system10 which provides the user with an optimized type of brushing action.Additionally, toothbrush system 10 allows for an internal liquidcontainer to be filled at the discretion of the user and allows simpleremoval therefrom.
